“…The first rubber dam was developed in the mid‐1950s for the Los Angeles Department of Water and Power. After that, it is widely used for water diverting and storage, irrigation, power generation, and urban river landscape construction (Islam & Kumar, 2016; Kumar & Islam, 2019; Tam, 1998; Zhang et al, 2002). Many researchers have analyzed the cross‐sectional equilibrium configuration and tensile force of the water‐inflated rubber dam (Tam, 1997; Zhang et al, 2002) and air‐inflated rubber dam (Ghavanloo & Daneshmand, 2009; Streeter et al, 2015; Watson et al, 1999).…”

The air-inflated rubber dam is innovatively adopted in this paper for temporary flood-fighting at the subway entrance. Numerical studies using the FLAC 2D software are carried out to investigate the behavior of the proposed structure. Laboratory model tests are also conducted to verify the accuracy of the numerical model. The results from the model tests agree well with those from the numerical analysis. Parametric studies are carried out to investigate the influences of the external floodwater head, inflated air pressure, and anchor position on the performance of the proposed air-inflated rubber dam. It is found that the external floodwater head reduces the tensile force but nonlinearly increases the height of the rubber dam. The inflated air pressure has no obvious effect on the cross-section of the rubber dam but heavily influences the ultimate flood-fighting height and tensile force. An optimum design line for the inflated air pressure of the rubber dam is provided. A deeper anchor position results in a smaller ultimate flood-fighting height. A rubber dam design with a lower anchor depth that has to satisfy the requirements of the anchor bolt is therefore concluded.

“…Thus, inflatable structures are used in construction and civil engineering fields. For example, inflatable rubber dams and silt fences are often used for water control [23], [24]. Inflatable structures can be used for temporary constructions such as tents and antennas [25], [26]; furthermore, they can be used to construct large structures given their light weight [27].…”

Soft robotics has recently become a popular topic owing to its advantages over conventional rigid robotics. In this article, we introduce a soft robot that can grow with its own structure; its main components include an inflatable tube for its body and a tip with an expansion mechanism. The tube is made of conventional laminated film. It leads the robot to improved applicability. The robot can grow along the horizontal and vertical directions, and it can bend around yaw and pitch axis. To achieve this, a mechanism feeds air into the inflatable tube for growing the structure, and another heat welding mechanism allows producing bending points where necessary. The experimental results confirm that the proposed robot can grow in mid-air and bend around the yaw axis with varying bending radii. Further, the robot can climb a wall and displace an upper surface by pitch-axis bending. The designed bending structures are very stable because of heat welding; the growing and climbing capabilities depend on the inner pressure of the tube, and these capabilities allow the robot to select various shapes and move seamlessly in various environments.
